Glass Cutting Tools (2018) Optical Mirror Academy

Did You Know There's a First Surface Mirror and other good project parts inside Rear Projection TV's?
This is the third video in the "Did You Know" series.
I dismantle and show what you can find and reuse from an old rear projection tv.
I've used the mirrors for making kaleidoscopes and some of the front screen elements to make lamp shades in the past.
Taking apart old appliances is a great way to get free supplies for your projects.

Both of the twin 20" quartz telescope mirrors are finished. Gordon puts the "A" disk on the test stand and shows how the Foucault test and the Ronchi test look. This mirror's test is reported by FigureXP to be better than /30th-wave, with a Strehl ratio better than 0.98. This is one of the mirrors that Gordon wrote about in the Cloudy Nights thread entitled "Making twin 20" quartz mirrors."

This is the first in a series of tests for developing an optical telescope mirror from a strash can lid. The optical aberration is dramatically reduced with the addition of a shroud creating an f-stop for the mirror at the lens surface. The image was cast off axis on a piece of wafer board.
